BlogFrom Wikipedia, the free encyclopediaA blog (a portmanteau made by contracting the phrase "web log") is a website in which items are posted on a regular basis and displayed in reverse chronological order. Like other media, blogs often focus on a particular subject, such as food, politics, Cole or local news. Some blogs function as online diaries. A typical blog combines text, images, and links to other blogs, web pages, and other media related to its topic. Since its appearance in 1995, blogging has emerged as a popular means of communication, affecting public opinion and mass media around the world.

Blogs can be hosted by dedicated blog hosting services, or they can be run using blog software on regular web hosting services.
